ADVANTAGES OF JSPL PARALLEL FLANGE BEAMS & COLUMNS ROLLED WITH UNIVERSAL ROLLING TECHNOLOGY

Wide Range: Widest product range available in the country lending more flexibility to designers and a more cost- e ective option to project owners

Exceptional Sectional Properties: Better sectional properties as compared to conventional tapered flange beams leading to e cient design and lower steel usage. Availability of hi-tensile steel grades enables designers/ users to further cut on steel tonnage

Steel Saving: Steel savings with parallel flange sections under bending load as well as under axial compression are appreciable when compared with tapered flange sections enabling usage of lower beam sizes

Higher Load carrying capacity: Exhibits higher load-carrying capacity with Parallel Flange Beams • sections under direct compression (when used as columns) owing to their higher radius of gyrationvalues about ‘y-y’ axis and reduced slenderness ratio of beams, thus increasing stress-bearing limits

Faster Construction: Simpler direct bolting of connections to flanges possible, as taper washers are not required. Flange-to-Flange welding possible as flanges are parallel

Ease in design: Enables complex design and fabrication in high volumes because of the inherent functional advantages of Parallel Flange Beams

Advantages Of Structural Section From Jspl

Economy – Steel savings with parallel flange sections under bending as well as axial load conditions are appreciable when compared with tapered flange sections

Excellent Durability - Due to clean steel quality, it is free from any harmful impurities and inclusions on account of in-house virgin raw material and state-of-art steel refining facilities

Superior Weldability – Due to its chemical composition of pure steel and lower carbon equivalent.

Product Range – Widest range available lending more flexibility to designers and more cost-e ective options to project owners.

Customised Length – Can be supplied in customised length which has helps in considerable amount of steel wastage reduction at consumer’s end.

Multiple Grades – Wide range of high value grades available providing good opportunity for consumers to opt for rolled sections and avoid built up sections.

ADVANTAGES OF HIGH STRENGTH STEEL (HSS):

As a thumb rule, every 1% increase in YS saves 0.5% of steel as enumerated below:

Potential savings in usage

Savings in steel cost considering additional prices for high strength steel

JSPL can supply all steel in High Strength Steel and is customized length. We can also collaborate to develop YS 550 MPa.

Advantages Of Jspl Beams Vs Tapered Flange Beam

Connections

E ects of tapered flange:

Bolted connection: Bolt shank gets bent on tightening from the origina straight alignment and

Welded connection: Only obtuse angled small thickness weld possible at the tapered tip

Tapered and narrow flange Indian sections result in two times more splice connection length compared to Parallel flange sections .

Sheet Pile

Sheet piles are thin interlocking steel sheets used to construct a continuous barrier in the ground to retain earth/water. Interlock is typically achieved by clutching the edge of one pile into the previous pile. Vibratory hammers are used to install sheet piles. Id the soil is too hard or dense, an impact hammer can be used to complete the installation. At certain sites where vibrations are a concern, sheets can be hydraulically pushed into the ground using silent pillar. Sheet piles are also a sustainable option since recycled steel is used in their construction and the piles can often be reused.
